CHICAGO -- A man is missing following a massive fire in Chicago’s Washington Park neighborhood.

Fire officials don’t know if the man made it out safely or if he never made it out of the building.

The search was suspended late Saturday morning, for a man in his 40s who was reported missing following a massive fire that took over two apartment buildings in the 5800 block of Prairie.

Firefighters believe the fire started in a red brick four-story building, which was vacant.

The landlord of the adjacent yellow brick building lives on the top floor and tells me, she made it out safely thanks to two police officers who noticed the fire while driving by, and started knocking on doors to get everyone out.

The tenants right below her—a woman, her son, and his girlfriend also made it out safety, but a man in his 40s who was visiting that family, is still unaccounted for.

When firefighters got to the scene, they searched the building, but were forced out by the flames.
